Event delegation is a technique of observing events on an ancestor
element (positioned "higher" in DOM) and exploiting events' bubbling
nature (ability of ancestor to catch event originated on its
descendant). It all just sounds complicated but essentially means
this:
document.observe('click', function(e) {
if (e.findElement('#myLinkId')) myFunction(e);
})
Now myFunction will be called only if user clicks on an element with
specified id (and simply ignoring everything else)
Hope this helps.
Best,
